That
is my defense: Leterrier's reasoning. Why? Because he's making the damn film. And in this film... in this "world"... it's what he is doing. It's not going to change.
"I really wanted to justify [Abominations] appearance. I really wanted to wrap my head around the original scaley-with-big-ears monster that was in the comic book, but I couldnt justify it. The guy isnt crossed with a fish; hes not crossed with a lizard. Just like the Hulk hes an über-human his body, everything, grows out. And the way he gets injected with the serum, hes shot in the skin and the muscles, and shot inside the spine. That makes his bones grow thicker and bigger and longer, making him a super-weapon. So hes got that spine that flares out, which becomes a weapon. Hes got elbows that stick out and become these martial arts, Chinese knives things that can slash back and forth. Hes got this tongue thing and the heel-spikes
so hes a killing machine. Its pretty cool, its funny. Hes got bones sticking out, so it becomes like an exo-skeleton which he uses as armour..."
Simple. Logical. Finite.
And as for "regular" movie goers... they don't know jack s**t about the character anyway. I highly, HIGHLY doubt that the average boob will walk out the theatre cursing and screaming at the screen "DAMN THAT LOUIS LETERRIER! ABOMINATION DIDN'T EVEN HAVE THOSE POINTY EARS! AND WHERE WERE THE SCALES?! WHAT AN OUTRAGE!!!"
Maybe if we're lucky, Abomination will turn out to be permawhite, too while he's at it.
